The dog was put back on to the property, but as Mrs Munro was being helped, the dog escaped and came back to attack her.
"I was terrified the dog was going to get me again."
The apologetic owners called Wanganui District Council's Animal Control who came to collect the dog.
The female animal control officer told Mrs Munro that any medical costs would be covered, and to keep all her receipts.
However Mrs Munro was now uncertain as to who was going to pay the costs for the ambulance, $20 for the Whanganui Accident and Medical Clinic visit, and medication.
ACC is covering her employment.
Mrs Munro suffered two puncture bites to the sole of her foot, one puncture bite on the top, and bruising, and has been on crutches and was unable to work at her Friday evening job.
She was not back at work yesterday and was doubtful that she would be able to work today.
Wanganui District Council customer services manager Melanie Heron said the dog was handed over to the council, which was going through the required process to have it destroyed.
Mrs Heron said the dog's owner has been asked to pay reparation to Mrs Munro.
She also advised that it was not necessary for Animal Control to call the police.
